Trouble with Ene's Scarf

I am in the middle of casting on for Ene's scarf for the third time! THe first time I missed a "pass stitch over" and couldn't ge the cast on row back on the needle when I tried to tink it back. This time I misunderstood the directions. The chart shows a section outlined in red and beneath that it says rep 11 times. Well, I thought that meant work that section once and then repeat 11 times for a total of 12. Guess what I found out when I got to the end of the row?? Yep, I didn't have enough stitches. So I went back and counted the stitches in the chart and figured out I should have 11 total not 12. In my mind you have to do something once before you can repeat it but I guess this is not the case in a chart. When directions are written out it will say something like *k1, p1, k1 p1* repeat from * to * 11 times which would mean work what is between the *'s once then 11 more times.

Well I am chalking it up to a learning experience because this is my firt try at lace. At least I am getting really good at the knitted on cast on!
